Police said one of the men, who was armed with a silver handgun, pistol-whipped the victim in his head and face.

The men then allegedly flipped over the victim's wheelchair, continuing to punch and kick him while he was on the floor.

The 39-year-old eventually gave the men $30 from his pocket, according to authorities.
